Letters Patent No. 110,177, dated December 13, 1870.

IMPROVEMENT in PUMPS.

The Schedule referred to in these Letters Patent and making part 9i' the same.

To a-Il whomfit may concern Be it known that I, ,WESLEY- G. WARD, of Fayette, in thefcounty of Seneca and State of N ew York, vhave invented certain Improvements in Pumps, of

which the following' is a specification, reference being lia-d to the accompanying drawing.

My invention relates to pumps, and consists in thel employment of a solid piston-head, of less diameter than the bore ofthe pump, in connection' with a single trap-valve at the bot-tom of thesame.'

In thedrawing- Figure l is a, longitudinal vertical section of my pump, and

Figures 2 and 3 are longitudinal vertical sections of modifications of the same.

. In the simplesttbrm of pumps heretofore constructed, it has been considered necessary to employ two valves, one in the bottoni ot' the pump and the other either iu the side of the pump or in the piston, and also to have the head of the piston so constructed or packed as to he water-tight between its periphery and the sidcs'of the pump. I have found by experiment that a good operative pump may be constructed with a single valve and the employment of a piston-head of less diameter that the bore of the-pump; andthat, in this way, a very. simple and 'cheap device can be produced. v

'I construct -thc barrel A of my pump B out of lany suitable materials,.:md ot' any size desired, and in or nearits bottom insert, in the usual way, au'ordinary trap- 'alve, (I.

ithin the barrel of the pump I place a. suit-able piston-rod', I), having-:L piston-head, E, of less diameter than the barrel, so as to leave an annular space about it as it moves upand down in the barrel.

The upper end `of the piston-rod I connect to any suitable'mechanical devices, whetherl a lever pumphandle, as shownin tig. l, or to a- T- handle, as shown in fig. 2, or a revolvingr shaft, as shown iu fig. 3.

In operating the pump, the space` between the pe-` riphery of the piston-'head and the inside of. the barrel, though being small, still allows the water to be forced through it asthe piston descends, and the same space, when the` piston .ascends, is` packed by the water itself. y

In experimenting on large scale, I have found no diiculty in using my pump successfully in wells thirtysix feet deep. I

When it is desired to raise a large quantity of water, the lower end of the bariel 0f the pump maybe enlarged, together with the valve andthe piston-head, as shown in tig. 3. In addition to the head on the bottom of the piston, other heads or disks, similar in form and size, may be placed upon it, as shown in g. 1. v

The advantages ot' this construction are obvious. It is ot' the simplest kind; there is no wear `on the piston-head, and the water itself furnishes all the packing required,

Having thus described my invention,

rIhe combination, in a 1iftp`ump,of a trap-valve, C, and valveless piston-liead E, of less diameter than the bore' otl the pump, substantially as herein de-.

scribed. v
